23.2 Extending gdb using Python

Python scripts used by gdb should be installed in
data-directory/python, where data-directory is
the data directory as determined at gdb startup (see Data Files).
This directory, known as the python directory,
is automatically added to the Python Search Path in order to allow
the Python interpreter to locate all scripts installed at this location.

Additionally, gdb commands and convenience functions which
are written in Python and are located in the
data-directory/python/gdb/command or
data-directory/python/gdb/function directories are
automatically imported when gdb starts.
